Microsoft "suddenly" does not seem to want you to run your own CI, which is a key part of running your own SCM. And this decision miraculously happens the moment a lot of big orgs are looking at self-hosting a cost effective (because open source) near 1:1 alternative to GitHub (=Forgejo).

So they make CI a bit cheaper but a future migration to Forgejo harder.

In fact they could easily pull off some typical sleazy Microsoft bullshit and eventually make it a shit ton harder to migrate out of GitHub once you migrated back in.
